| 摘 要： | 在灵石山100-900 m海拔梯度上米槠林分布的范围内,对米槠林优势种群不同年龄叶片的叶属性及其相关性进行分析。结果表明,叶属性有显著的叶龄间以及种间的差异;不同年龄叶片叶属性之间存在显著的相关性。说明叶片性状是植物长期适应环境的结果,叶片对不同环境的适应策略不同,不同年龄叶片对相同环境的适应策略也有差别,但各种环境下植物的各种叶片性状满足一定的关系,这种关系是植物适应环境的表现。

| Abstract: | Specific leaf area(SLA),leaf dry matter content(LDMC) and nutrient content of different age leaves were investigated along the altitudinal distribution gradient of dominant populations in Castanopsis carlessi forest in Lingshishan National Forest Park.Furthermore,the correlation between specific leaf area,leaf dry matter content and leaf nutrient content were analyzed.The results showed that the variation of different age leaves were existing in leaf traits.SLA was positively correlated with the leaf conten... |
